The right choice?

[stang2112]

Hello, Im starting a 600N build and was wondering what's the right purchase.

G770/BLS251--little pricy
G770/S9257
G770/S8900G
401/9254
or can the G770/9254 be compatable?

I plan to use for the other 4 servos the 9452!
Any suggestions...go ahead let me have it!!!!

The BLS251 is a non-starter as it will not work with the 770, it runs at too low a pulse width for it. I would strongly recommend the 8900g, this servo is intended for use with the 770 and they work very well together. The 401/9254 combo is good but not as good as the 770/8900g. The 9257 is a mini servo and not really suitable, you could use the 9254 with the 770 but I'd stick with the 770/8900g of the options you've quoted.
